1. INTRODUCTION

Background 1.1 Route 9 (Kowloon Section) (R9K) (hereinafter call the R9K-Project) forms part of the Route

9 between Cheung Sha Wan and Sha Tin (R9-CSWST) project, which will be a new expressway connecting West Kowloon and Sha Tin. It will be the fourth external link between Sha Tin and Kowloon and will form an important link between the northeast New Territories and the west Kowloon, Lantau Island and the western New Territories. R9K is being managed and implemented by the Highways Department (HyD).

1.2 The engineering design of R9K is covered under Agreement No. CE 50/98 “Route 9 between

Cheung Sha Wan and Sha Tin – Design Construction Assignment”. The main consultant engaged under Agreement No. CE 50/98 is Maunsell Hyder Joint Venture (MHJV), who will act as the Engineer for the construction contracts. The works of R9K mainly comprise a 1.4km dual 3-lane Lai Chi Kok Viaduct from Lai Wan Interchange to Butterfly Valley; 0.5 km of dual 3-lane at-grade carriageway linking to the 2.1 km dual 3-lane twin-bore Eagle’s Nest Tunnel with associated portal buildings; a toll plaza with an administration building located with the Sha Tin valley woodland; a ventilation building and an adit; associated noise barriers, noise enclosures, drainage, slope and landscape works; and electrical and mechanical works for the whole R9-CSWST. The remainder of the R9-CSWST forms the Sha Tin Section (R9S) of the project and is being managed and implemented separately by the Civil Engineering and Development Department (CEDD).

1.3 The R9-CSWST project is a Designated Project under the Environmental Impact Assessment

Ordinance (Cap. 499) (EIAO). An environmental impact assessment (EIA) report has been prepared in 1998 for the R9-CSWST project (1998 R9 EIA) to consider the key issues of noise, air quality, water quality, ecological, construction waste, landscape and visual, land use and cultural impacts, and identify possible mitigation measures.

1.4 An Updated Final EIA report was subsequently completed in September 1999 for the R9-

CSWST project (1999 R9 EIA), to cater for some changes in R9K portion as mentioned in paragraph 1 in the report. The 1999 R9 EIA was endorsed by Environmental Protection Department (EPD) in November 1999. The 1998 R9 EIA and the 1999 R9 EIA (R9 EIA Reports) were included in the EIA register under the EIAO as report no. EIA-135/BC and AEIAR-022/1999 respectively. Environmental Monitoring and Audit (EM&A) Manuals for each of the R9 EIA Reports (EM&A Manuals) were also included as part of the EIA reports in the register.

1.5 Subsequent to the endorsement of the R9 EIA Reports by EPD in November 1999, the

project programme was deferred to start in 2002/2003 for completion by 2006/07. The implementation of the project was then separated into the R9S and R9K portion. An Environmental Permit (EP) No. EP-103/2001 was issued on 17 September 2001 for R9K to the HyD as Permit Holder and a varied EP No. EP-103/2001/A was subsequently issued on 20 May 2003 for R9K (R9K EP) to HyD as Permit Holder. A varied EP-103/2001/C was recently issued on 22 July 2005.

Monitoring Methodology and QA/QC Procedure Instrumentation

2.5 Graseby GMW Model GS2310 TSP High Volume Sampler (HVS) was employed for 1-hour & 24-hour TSP monitoring. The sampler was composed of a motor, a filter holder, a flow controller and a sampling inlet and its performance specification complied with that required by USEPA Standard Title 40, Code of Federation Regulations Chapter 1 (Part 50). Moreover, the HVS also met all the requirements in Sections 2.2 to 2.4 of the EM&A Manual (1999).

Operating/Analytical Procedures

2.6 Operating/analytical procedures for the operation of HVS were as follows:

• A horizontal platform was provided with appropriate support to secure the samplers

against gusty wind. • No two samplers were placed less than 2 meters apart. • The distance between the sampler and an obstacle, such as buildings, was at least twice

the height that the obstacle protrudes above the sampler. • A minimum of 2 meters of separation from walls, parapets and penthouses was required

for rooftop samples. • A minimum of 2 meters separation from any supporting structure, measured horizontally

was required. • No furnaces or incineration flues were nearby. • Airflow around the sampler was unrestricted. • The sampler was more than 20 meters from the drip line. • Any wire fence and gate, to protect the sampler, should not cause any obstruction during

monitoring.

2.7 Prior to the commencement of the dust sampling, the flow rate of the high volume sampler was properly set (between 1.1 m3/min. and 1.4 m3/min.) in accordance with the manufacturer's instruction to within the range recommended in USEPA Standard Title 40, CFR Part 50.

2.8 For TSP sampling, fiberglass filters (G810) were used.

2.9 The power supply was checked to ensure the sampler worked properly.

2.10 On sampling, the sampler was operated for 5 minutes to establish thermal equilibrium before placing any filter media at the designated air monitoring station.

2.11 The filter holding frame was then removed by loosening the four nuts and a weighted and conditioned filter was carefully centered with the stamped number upwards, on a supporting screen.

2.12 The filter was aligned on the screen so that the gasket formed an airtight seal on the outer

edges of the filter. Then the filter holding frame was tightened to the filter holder with swing bolts. The applied pressure should be sufficient to avoid air leakage at the edges.

2.13 The shelter lid was closed and secured with the aluminum strip.

2.14 The timer was then programmed. Information was recorded on the record sheet, which

included the starting time, the weather condition and the filter number (the initial weight of the filter paper can be found out by using the filter number).

2.15 After sampling, the filter was removed and sent to the laboratory for weighing. The elapsed time was also recorded.

2.16 Before weighing, all filters were equilibrated in a conditioning environment for 24 hours. The conditioning environment temperature should be between 25°C and 30°C and not vary by more than ±3°C; the relative humidity (RH) should be < 50% and not vary by more than ±5%. A convenient working RH is 40%.

Maintenance/Calibration

2.17 The following maintenance/calibration was required for the HVS:

• The high volume motors and their accessories were properly maintained. Appropriate maintenance such as routine motor brushes replacement and electrical wiring checking were made to ensure that the equipment and necessary power supply are in good working condition.

• High volume samplers were calibrated at bi-monthly intervals using GMW-25 Calibration Kit throughout all stages of the air quality monitoring.

Results and Observations 2.18 All TSP monitoring was conducted as scheduled in this reporting month. No Action/Limit

Level exceedance for both 1-hr and 24-hr TSP was recorded in the reporting month. 2.19 Wind data monitoring equipment has been installed in Shatin Heights for logging wind speed

and wind direction. These wind data for the reporting month is summarized in Appendix D. 2.20 The monitoring data and graphical presentations of 1-hour and 24-hour TSP monitoring

results are shown in Appendices E and F, respectively.

3. NOISE

Monitoring Requirements 3.1 Monitoring and audit of construction noise levels is required to be conducted, in accordance

with the EM&A Manual, to ensure that any unacceptable noise impacts could be readily detected and timely and appropriate action be undertaken to rectify the situation.

3.2 The construction noise levels shall be measured in terms of the A-weighted equivalent

continuous sound pressure level (Leq). Leq (30min) shall be used as the monitoring parameter for the time period between 0700-1900 hours on normal weekdays. For all other time periods, Leq (5min) shall be employed for comparison with the Noise Control Ordinance (NCO) criteria. As supplementary information for data auditing, statistical results such as L10 and L90 shall also be obtained for reference.

3.3 Five designated noise monitoring stations, namely NM2, NM4, NM8a, NM8b and NM9

were selected for impact monitoring. Appendix A shows the established Action and Limit Levels for the environmental monitoring works.

Monitoring Locations

3.4 Noise monitoring was conducted at five designated monitoring stations as summarized in Table 3.1. Figures 1 show the locations of these stations.

Table 3.1 Noise Monitoring Stations

Stations(1) Description Location

NM2 Lai Chi Kok Correctional Institution Rooftop

NM4 Mei Foo Sun Chuen, Phase 5 Rooftop of Block 9

NM8a Nob Hill M/F of Car Park

NM8b Nob Hill 3/F of Car Park

NM9 Hoi Lai Estate G/F of Hoi Fai House (1) The Lai Chi Kok Hospital (NM3) was also found vacated and noise monitoring has been suspended since

January 2005, as approved by EPD on 15th March 2005.

3.5 Stations NM8a and NM8b were installed at Nob Hill in May 2004. Station NM8b is located at 3/F of the car park of Nob Hill, which is strongly influenced by traffic noise from Ching Cheung Road. The measurement at this station is for reference purpose, but not for compliance check of construction noise. The measured noise level at Station NM8a, which is located at M/F of car park and closer to the construction site, acts as an indicator of the construction noise. Since the domestic premises are located above 5/F, noise assessment would be performed to assess the level of nuisance resulting from the construction noise at the domestic premises whenever the measured noise level at NM8a exceeds the noise limit level.

3.6 The noise monitoring at Lai Chi Kok Correctional Institution (NM2), which was formerly known as Lai Chi Kok Reception Centre, has been resumed since 8th September 2006 after the completion of the renovation works.

3.7 A new housing estate, Hoi Lai Estate, became one of the noise sensitive receivers close to the

Project site. As recommended by the Regional (West) Office of EPD, noise monitoring at this location (Station NM9) was newly included in the EM&A programme. Approval for the change of EM&A programme was granted by EPD on 30th December 2004.

Monitoring Methodology and QA/QC Procedures • The Sound Level Meter was generally set on a tripod at a height of 1.2 m above the

ground, depending to the actual monitoring condition. • The battery condition was checked to ensure the correct functioning of the meter. • Parameters such as frequency weighting, the time weighting and the measurement time

were set as follows: — frequency weighting : A — time weighting : Fast — time measurement : 30 minutes / 5 minutes

• Prior to and after each noise measurement, the meter was calibrated using a Calibrator for

94.0 dB at 1000 Hz. If the difference in the calibration level before and after measurement was more than 1.0 dB, the measurement would be considered invalid and repeat of noise measurement would be required after re-calibration or repair of the equipment.

• The wind speed was frequently checked with the portable wind meter. • At the end of the monitoring period, the Leq, L90 and L10 were recorded. In addition, site

conditions and noise sources were recorded on a standard record sheet. • Noise measurement was paused during periods of high intrusive noise if possible and

observation was recorded when intrusive noise was not avoided. • Noise monitoring was cancelled in the presence of fog, rain, and wind with a steady

speed exceeding 5 m/s, or wind with gusts exceeding 10 m/s.

Maintenance and Calibration 3.10 The microphone head of the sound level meter and calibrator was cleaned with soft cloth

regularly. 3.11 The meters were sent to the supplier to check and calibrate on a yearly interval.

Results and Observations 3.12 Noise monitoring was performed at the five designated locations (NM2, NM4, NM8a, NM8b

and NM9) as scheduled in the reporting month. 3.13 All the Construction Noise Levels (CNLs) reported in this report, except those collected at

Stations NM8a, NM8b and NM9, were adjusted with the corresponding baseline level (i.e. Measured Leq – Baseline Leq = Measured CNL), in order to facilitate the interpretation of the noise exceedance.

3.14 Noise monitoring results and graphical presentations are shown in Appendix G. 3.15 No Action/Limit Level exceedance was recorded in the reporting month. 3.16 At Stations NM8a and NM8b, the major noise source identified during the monitoring

exercises was mainly the road traffic noise. 3.17 At Stations NM2, NM4 and NM9, construction noise from the Project and occasionally the

traffic noise were identified as the major noise source during monitoring.

4. ENVIRONMENTAL AUDIT

Site Audits 4.1 Site audits were carried out by ET on weekly basis to monitor the timely implementation of

proper environmental management practices and mitigation measures in the Project site. The summaries of site audits are attached in Appendix I.

4.2 Site audits for Civil contract were conducted on 5th, 12th, 19th and 28th December 2007. A joint site audit for Civil works was conducted on 5th December 2007 with representatives from IEC, ER, the Contractor and ET while the joint site audit for TCSS works was conducted on 5th December 2007 with the representatives from IEC, ER, the Contractor and ET. No environmental deficiency was recorded for TCSS contract during site inspections.

Review of Environmental Monitoring Procedures 4.3 The monitoring works conducted by the monitoring team were inspected regularly. The

following observations have been recorded for the monitoring works:

Air Quality Monitoring

• The monitoring team recorded all observations around the monitoring stations within and outside the construction site.

• The monitoring team recorded the temperature and weather conditions on the monitoring days.

Noise Monitoring • The monitoring team recorded all observations around the monitoring stations, which

might affect the monitoring result. • Major noise sources were identified and recorded. Other intrusive noise attributing to the

result was trimmed off by pausing the monitoring temporarily.

Status of Environmental Licensing and Permitting 4.4 All valid permits/licenses obtained for the Project are summarized in Table 4.1. Five new

CNPs were issued to the Project in the reporting month.

Implementation Status of Environmental Mitigation Measures 4.5 According to the Environmental Permit and the EM&A Manuals, the mitigation measures

detailed in the documents are required to be implemented. An updated summary of the EMIS is provided in Appendix K.

6. CONCLUSIONS AND RECOMMENDATIONS

Conclusions 6.1 Environmental monitoring works were conducted in the reporting month and all monitoring

results were checked and reviewed. 6.2 No Action/Limit Level exceedance for both 1-hour TSP and 24-hours TSP was recorded in

the reporting month. 6.3 No Action/Limit Level exceedance for noise was recorded in the reporting month. 6.4 No public complaint was received in the reporting month. 6.5 No prosecution was received in the reporting month.

Recommendations

6.6 According to the environmental audit performed in the reporting month, the following recommendations were made: Water Impact • To ensure properly maintenance for de-silting facilities • To review the capacity of de-silting facilities for discharge. • To avoid stagnant water accumulation on site. Noise Impact • To provide temporary noise barriers for noisy activities, such as slope upgrading works

for Feature No. 11NW-A/FR 54 & A/FR55 • To review the works sequence of site activities so as to reduce the number of noisy

equipment in concurrent operation. • To employ quiet powered mechanical equipment if possible. • To ensure compliance of CNP conditions during restricted-hour works. Dust Impact • To ensure water spray is applied for the dust emissive works, such as slope upgrading,

loading and unloading of soil materials. • To cover soil stockpiles and exposed slope surface by impervious sheets or other means. • To ensure that all vehicles carrying dusty material are properly covered before leaving

the site. Waste / Chemical Management • To ensure the performance of sorting of C&D materials at source (during generation); • To carry out inspection of dump truck at site exit to ensure inert and non-inert C&D

materials are properly segregated before removing off site. • To ensure proper collection and disposal of rubbish generated on site. • To avoid any discharge or accidental spillage of chemical waste directly from the site.

• Landscape mitigation measure 1 (LMM1) – Construction programming and management. The periphery of the works areas at street level shall be managed so that they do not appear cluttered, untidy and unattractive and inconvenient to pedestrians. For example, all hoarding shall be colorfully designed with interesting motifs demonstrating the work of Highways Department. Hoardings with bland colours shall be avoided.

^

• Landscape mitigation measure 2 (LMM2) – Advanced planting and erosion control works. Where possible, the transplantation of existing valuable trees, the stockpiling of topsoil, new planting and erosion control works shall be carried out as early as possible in the construction period instead of at the end. This will assist in maximizing the time for carrying out transplantation and new planting, resulting in a higher success rate for the survival of transplantation and new planting, resulting in a higher success rate for the survival of transplanted trees and the establishment of new screen trees. The stockpiling of topsoil will provide an abundant use of on-site material for growing media. During detailed design, the issue of stockpiling of topsoil in a manner that would avoid washing into the drainage scheme should be examined comprehensively.

^

Landscape and Visual Impact

• Measurement of vibration would also be carried out on a need basis during the piling work ^ Remarks:

^ Compliance of mitigation measure;

X Non-compliance of mitigation measure;

N/A Not Applicable; • Non-compliance but rectified by the contractor

Appendix M - Complaint Log

Log Ref. Location Received Date Details of Complaint Investigation/Mitigation Action Status

40318 Nob Hill 18 March 2004

Kwai Tsing District Officer (KTDO) recently received a public noise complaint about construction noise generated from the Route 8 – Lai Chi Kok Viaduct (R8-LCKV) Project, near Nob Hill, Lai Chi Kok. KTDO referred the complaint to the Highways Department (HyD) on the same day. HyD subsequently referred the complaint to the Environmental Team (ET) Leader of the Project on 18 March 2004. The complaint was raised by the Citybase Property Management Ltd. (the management company of Nob Hill) and the Secretarty of Nob Hill Owners Committee (Mr. Kevin Tse) about construction noise generated from the R8-LCKV Project at the work areas near Nob Hill. Mr. Kevin Tse mentioned that residents living in Nob Hill have greatly been affected by the noise impacts generating from the R8-LCKV construction works. He also requested relevant government departments to consider installing noise barrier along Ching Cheung Road and to work out possible measures to minimize the noise nuisances to the residents living in the vicinity.

Based on the information provided by the ER, the construction activities conducted in the vicinity of Nob Hill in the period between 2 and 18 March 2004 were:

Item 1 – Breaking off existing planter and excavate trial trench to expose underground utilities (using one to two backhoes) Item 2 – Erect rock fall fence & forming platform for pre-

drilling (using one backhoe and occasionally one crane lorry) Item 4 – Excavate further to expose all underground utilities

(using hand tools) Item 5 – Pre-drilling works (using one drilling rig)

Considering the scale of work and the PMEs adopted, the ET believed that the construction noise impact at Nob Hill from the above construction activities of R8-LCKV was not significant. The bored piling work (Item 3) using one crawler crane and one oscillator was started on 19 March 2004, which was two days after the issue date of this complaint, so this activity was not considered in this report. According to the EM&A Manuals, Nob Hill was not selected as Noise Monitoring Location (NML) for the Project. Therefore, no direct noise monitoring data could be provided for the complaint investigation. However, there was no noise level exceedance recorded at the nearby NML (NM4 – Mei Foo Sun Chuen, Phase 5) since the commencement of the project according to ET’s inventory. During ET’s weekly environmental site inspections on 3, 10, 17 March 2004, no serious noise nuisance induced by the Project works was observed at the sites near Nob Hill.

40330 Site Areas near Nob Hill 30 March 2004

Highways Department (HyD) recently received a public noise complaint about construction noise generated from the Route 8 – Lai Chi Kok Viaduct (R8-LCKV) Project, near Nob Hill, Lai Chi Kok. HyD referred the complaint to the RSS and subsequently referred to the ET Leader of the Project on 30 March 2004. The complaint was raised by Mr. Yau, the Office of DCV Member Mr. Cheung Wing Shum, regarding the high pitch construction noise generated at the R8-LCKV site which cause serious nuisance to the residents at Mei Foo.

Based on the information provided by the RSS, the Contractor was not aware of any high pitched construction noise arising from plant employed for their works. The noise complaint referred to may be originated from the damage of a gas main valve on the afternoon of 29 March 2004 in the vicinity of the junction of Mai Lai Road with Lai King Hill Road. The high pitched whistle apparently resulted from the damage which was repaired by TownGas in that afternoon. Based on the information obtained, this noise complaint is considered not due to the construction activities of the Project. Nevertheless, the Contractor was recommended to adopt good site practice to minimize the construction noise, such as: • To space out noisy equipment and position it as far away as

possible from the sensitive receivers; • To avoid concurrent uses of noisy equipment near the

sensitive area; • To ensure the equipment are maintaining in good operation

NECSO referred the complaint to the RSS and subsequently referred to the ET Leader of the Project on 6 April 2004

The complaint was raised by Ms Wong, regarding the noise generated from the Ching Cheung Road Widening Works of the R8-LCKV Project, which cause serious nuisance to her. Based on the information provided by the RSS, the plants employed by the Contractor for carrying out bored piling works in front of Nob Hill should not generate excessive noise. The RSS had also checked against the site records that no piling works was in progress in front of Nob Hill on 1-3 April 2004. According to telephone communication between the complainant (Ms Wong) and the RSS on 8 April 2004, the RSS reported that Ms Wong was not complaining about the construction noise generated by the R8-LCKV Project. She was actually complaining about the traffic noise she anticipated to be generated after completion of widening work at Ching Cheung Road in front of Nob Hill.

Log Ref. Location Received Date Details of Complaint Investigation/Mitigation Action Status The complainant was particularly concerned about the fugitive dust emission during rock / concrete breaking activities.

Observations On 1 Jun 05, one of the environmental deficiencies noted by the ET was about fugitive dust emission from breaking activities at CCR-R3. The Contractor was reminded to provide sufficient dust mitigation measures for the breaking works. Immediate action was taken by the Contractor to apply water spray for the works as observed during the audit session. On 9 Jun 05, the breaking works were still being taken at CCR-R3. Water spray as a dust mitigation measure was being adopted by the Contractor during the audit. No observable dust emission was noted from the breaking works or other site activities. On 15 Jun 05, the same area was re-inspected due to the receipt of the complaint from EPD. The demolition works had been finished and no other dust emissive activity was being taken. No other dust source from the construction site was observed during the inspection. Conclusion Based on the observations noted during our site inspections, this complaint is considered to be valid and related to the construction activities of the Project. However, corrective action had been taken by the Contractor and the situation was found improved during the follow-up inspections.
